采用(概率×规模)对隧道塌方风险进行定义,建立隧道塌方风险评价模型,对风险因素进行量化,利用模糊数学建立各风险因素对于塌方概率和塌方规模的隶属函数,运用乘积标度法确定每个因素对塌方的影响权重,对隧道塌方风险的评估过程和方法进行详细的阐述,并在实际应用中进行了探讨。
The probability of landslide hazard is defined by (probability × scale), and the tunnel collapse risk assessment model is established. The risk factors are quantified. The membership function of each risk factor for landslide probability and landslide scale is established by using fuzzy mathematics. The factors that influence the landslide are described in detail. The assessment process and method of tunnel landslide risk are described in detail and discussed in practical application.
